Implement Browser Caching Headers
High Impact+18 points estimated
Why It Matters
Missing cache headers force re-downloading 5,148 KiB on repeat visits, slowing LCP by 6.55 seconds.
How to Fix
Add Cache-Control headers with max-age=31536000 for static assets like images and CSS. Configure your web server or CDN to set Expires headers for PNG, CSS, and JS files. Add ETags for better cache validation.

AI Performance Analysis
This website has poor performance with a score of 61/100, primarily due to extremely slow loading times with pages taking 8.8 seconds to become fully interactive. The biggest issue is massive, unoptimized images (over 5MB total) that lack proper caching, modern formats like WebP, and appropriate sizing for their display dimensions. The site also suffers from render-blocking CSS and JavaScript files that delay the first paint by 1.8 seconds, plus 275KB of unused JavaScript code. Fixing image optimization, implementing proper caching headers, and removing unused code could dramatically improve performance by reducing load times by several seconds and boosting the performance score by 25-30 points.
Other Optimization Recommendations
Optimize and Convert Images
High Impact+25 points estimatedWhy It Matters:
Large PNG images waste 4,217 KiB and delay LCP by 3.25 seconds.
How to Fix:
Convert group-photo.png and werewolf PNG files to WebP format for 70-80% size reduction. Resize images to match display dimensions (427x427 for group photo, 160x160 and 192x192 for werewolves). Use responsive image srcset to serve appropriate sizes for different screen sizes.
Eliminate Render-Blocking CSS
Medium Impact+12 points estimatedWhy It Matters:
CSS files block initial render for 1.82 seconds, delaying First Contentful Paint.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Load non-critical CSS asynchronously using media='print' onload='this.media="all"' technique. Preload Google Fonts with link rel='preload' to reduce font loading delays.
